This research focuses on exploring the travel attitude, personality lifestyle, and mobility factors affecting individuals' vehicle type choices, as well as developing a disaggregate choice model of vehicle type based on both these factors and typical demographic variables. A literature review looks at studies related to vehicle type choice models, vehicle use models, and mobility. The study then describes the characteristics of vehicle classification model used in the study, and the key explanatory variables included in the vehicle type choice model. The relationships of vehicle type to travel attitude personality, lifestyle, mobility, and demographic variables are then individually examined u sing one-way ANOVA and chi-squared tests. A multinomial logit model is then developed for vehicle type choice.
